Getting long in the tooth at this point, and somewhat officious rather than personal, the Mayaland is less than 100m from Chichén Itzá and has a 'private' entrance. The rooms are good, however, and the expansive public areas attractive, though there's actually very limited benefit in being so close to the site, unless you plan to visit multiple times.
As well as restaurants and all the services, it also offers cultural programs, including a popular 'Be Maya' activity where you cook Maya cuisine plus visit the resort's own replica 'observatory,' while learning about the roles of Maya people.
